DOUBLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,055, dated November29, 1887..

Application filed May 18, 1887. Serial No. 238,572. (No model.)

p which- Figure 1 is a perspective diagram illustrating the essentialparts of the machine. Fig. 2 is a view,partly in section and partly inelevation,of an organized machine constructed in accordance with myinvention. Fig. 3 isaplan view of said machine. Figs. 4 and 5 aredetached views of parts of the machine, and Fig. 6 a side view showing aslight modification in one of the elements of the machine.

In my improved machine I simultaneously effect the doubling of thestrands and the winding of the doubled yarn upon a spindle to form thecop.

Referring to Fig. 1 of the accompanying drawings, 1 represents thespindle upon which the cop is to be wound, said spindle being of squareor other polygonal form in cross-section and being free to slide in asleeve, 2,which is adapted to suitable bearings in standards 3 on thefixed frame '4 of the machine, and is provided with a fast pulley, 5,and loose pulley 6, for receiving the driving-belt.

The. strands 8, which are to form the doubled strand 9, are drawndirectly. from the skeins or hanks 10,and pass between an upperfeedroll, 11, and lower feed-rolls, 12 and 13, and thence through aguide-eye, 14, to a traveler, 15, on a ring, 16, carried by the pivotedend of one arm of a traverse lever, 17, which is mounted upon a shaft orspindle, 18, the other arm of thelever havinga slotted 1ink,19, whichembraces a shaft, 20, carrying a heart-cam,21, the latter acting upon ananti-friction roller, 22, on the link,which roller is maintainedcontinually in contact with the surface of the cam by means of a coiledspring, 23, connected at one end to the link and at the opposite end toa fixed eye on the frame. This gives a short traverse for carrying theyarn from the bottom to the top of the cop-nose. the slow retraction ofthe spindle, so as to effect the gradual ad-, vance of the successivecourses of yarn upon the same,being effected by means of a frame, 24,the upper bar of which is free to slide longitudinally and to swing inbearings in the standards 3, and is connected by a link, 25, to the rearend of the spindle 1, said link having a set-screw, 26, adapted to agroove, 27, in the top bar of the frame 24, as shown in Fig. 4,so thatwhile the spindle 1, must partake of any longitudinal movement of saidframe the latter can be swung up or down without restriction. Theconnection between the link 25 and the spindle 1 is also similar to thatshown in Fig. 4, so that said spindle is free to rotate.

The lowerbar of the frame 24 has a rack, 28, with which engages a worm,29,0n a shaft,30, adapted to hearings in brackets 31 on the frame 4 anddriven at a slow rate of speed, so that as the yarn is laid upon the copthe spindle 1 will be slowly retracted and the successive layers of yarnproperly disposed thereupon.

When the cop is fully formed, the frame 24 maybe swung upward by meansof a handle, 32, so as to release the rack 28 from the control of theworm 29, the pivoted guide-eye 14 and the pivoted upper end of thetraversearm, with its ring and traveler, being then thrown d9yvn,asshownin Fig 5,so as to permit the doffing of the cop from tl e spindle.After the cop has been doffed,the pivoted guide-eye and the ring arerestored to their former positions, the spindle is drawn forward, andthe frame 24 again swung down, so as to effect the re-engagement of therack with the worm preparatory to a repetition of the operation.

It will be seen that by the use of the ring and traveler on thetraverse-motion device the twisting or doubling of theindependentstrands is effected simultaneously with the winding of the doubled yarnupon the spindle to form the cop, all preliminary spooling operationsbeing dispensed with.

That portion of the spindle 1 on which the yarn is wound should in allcases be of such diameter. that the yarn in passing from the traveler tothe spindle will assume such an angle as to insure the pulling of thetraveler around the ring.

IOU

In Figs. 2 and 3, which show the complete machine constructed inaccordance with my invention, 4 represents the fixed frame, which hassuitable bearings for the reception of the driving-shaft 35, thelatterhaving a pulley,36, which receives the belt from any availablecounter-shaft. The shaft 35 also has a pulley, 37, which receives abelt, 38, the latter, by

means of any suitable form of belt-shifter, be-

ing applied either to the fast pulley 5 or the loose pulley 6 on thesleeve of the spindle 1. On the shaft 35 is also a pinion, 39, whichengages with a spur wheel, 40, on a sleeve, 41, carried by a stud,42,011 the frame, said sleeve having a pulley, 43, which receives abelt, 44, adapted to a pulley, 45, on a shaft, 46, thelatter having abevel-wheel, 47, engaging with a bevel-pinion, 48, on the worm-shaft 30.The shaft 46 is also provided with a pulley, 49, which receives a belt,50,driving a pulley. 51, on the cam-shaft 20, and on the driving-shaft35 is a pulley, 52, receiving a belt, 53,which is adapted to a pulley,54, on a sleeve carrying a pinion, 55, which engages with a spur wheel,56, on the shaft of the lower feed-roll l2, spurpinions 57 and 5S, andan intermediate spurwheel, 59, transmitting movement to the other of thelower feed-rolls. 13. The hanks are carried by the reels 60, which areadapted to bearings in brackets 61 on the frame of the machine.

The pivoted upper end of the arm of the le ver 17,which carries the ring16, is acted upon by a spring, 65,which tends to maintain said pivotedend either in the position shown in Fig. 2 or in the depressed positionshown in Fig. 5.

If desired, the ring 16 and its traveler may be carried by a slidingbar, 70, operated by a cam, 21, and lever 17, as shown in Fig. 6,instead of being applied directly to the lever, as in Figs. 1 and 2.

I claim as my invention- 1. The combination of the spindle and means forrotating and slowly traversing the same,with a traverse-motion devicehaving a ring and traveler, and with means for operating the saidtraverse-motion device, all substantially as specified.

2. The combination of the spindle and mechanism for rotating and slowlytraversing the same, a traverse-motion device having a ring andtraveler, a set of feed-rolls, and means for operating said feed-rollsand the traversemotion device, all substantially as specified.

3. The combination of the spindle and mechanism for rotating and slowlytraversing the same, a traverse-motion device having a ring andtraveler, a set of feed-rolls, hangers for two or more sets ofskein-reels, and means for operating the feed-rolls and traverse-mo tiondevice, all substantially as specified.

4. The combination of the spindle and worm and means for rotating thesame, with a swinging frame connected to the spindle and having a rackmovableinto or out of engagement with the worm, all substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
